    EcoBoost Engine Flaw?

    From the Saturn forum I frequent:

    Quote Originally Posted by jeep45238
    Picture of the 3.5L ecoboost 340 hp turbo direct-injected gasoline V6 they'll be introducing this year. It seemed pretty promising, bigger engine, more economy, less emissions, lots more power. Ecoboost is what they're calling the engine line, which will also have 4 cylinders in it.

    Until I saw that picture. WHY didn't they learn from Chrysler's mess with the 2.7L V6? The damn water pump is inside the block (dead middle pulley - the lower one is the oil pump). When that gasket goes or it starts leaking, odds are the whole engine will have to be replaced or rebuilt. A couple hour job to the tune of under 200 bucks is now well over 2000 and hours on end considering how packed they're probably going to make the engine bay.

    I'll pass on this one, and frankly, I wouldn't be surprised if they get a class action lawsuit against them like Chrysler did. I'm still astounded how 'engineers' this stupid get handed projects like this and they come out the door fatally flawed from the get go.

    Re: EcoBoost Engine Flaw?

    when i was working in a ford dealership, you wanna know how often i replaced a waterpump on ford models within the last 6 years, not one. Plus if you do your maintenance and flush the coolant system at required intervals it reduces the chance of having issues, most issues with coolant systems is lack of maintenance, coolant can almost turn acidic and cause corrosion thus creating leaks and wear out bearing in a water pump.

    First, this has nothing to do with EcoBoost. The water pump is in the same location on all 3.5/3.7L Duratec engines.

    Second, when I saw this engine for the first time about 5-6 years ago (yes, a couple of years before production) I said the same thing. The answer I got was there a weep holes designed in so that if the water pump starts leaking, the water will have an exit path and NOT wind up in the pan !

    Millefune, would you be so kind and pass theoldwizard's info over to the good guys from the Saturn forum you frequent?

    Thank you

    I think you're right, I know that duratec has a belt driven waterpump on the left head at the rear of the engine powered by the cam.

    Can you fix the grammar and spelling so I can quote you and let the people on the other forum know?

    What does this have to do with a saturn forum?

    I did a search on the ecoboost v6 I do believe that picture is correct

    the difference here its that Fords parts quality doesnt suck like Chrysler ones and I know this by personal experience with my mom 2 last Chrysler products vs our Fords

    For a rear seal leak - maybe........front seal or mounting surfaces ????

    Looking at the picture........... you want to try that one again ????

    Water pump 'weep holes' - to where ???

    If there isn't something more to it - like tubing to route it outside the area behind the chain cover......... you're still dumping it in the oil but in the front cover area just below the pump.

    Yea, so not exactly into the pan ala Chrysler - you got about a 3 -10 second delay before it hits the pan if running less if not - so what, its still going to be mixing oil and coolant with the right kind of failure.

    *****************************

    Calling this water pump installation a flaw is purely subjective.

    Its really just a matter of personal preference.

    If they run out fine or at least acceptably long enough - no harm no foul.

    Since the 3.5/3.7 have not received any problems so far and they have been running around two years now, Im willing to bet the EB will be just as good in quality as the non-EB.

    Look, I wasn't the design engineer. I'm telling you what I was told. The issue was brought up early in the design phase and it was handled. What more can I say !

    Is this a "perfect design ? Heck no ! If the pump does fail, you going to have to remove the front cover, so add an hour or 2 to the flat rate time.

    Is it possible under some failure modes for coolant to leak into the pan ? Probably !

    Life is a compromise.

    Re: EcoBoost Engine Flaw?

    The Domestic three have been using some pretty long time high mileage durability standards in their various power train programs.

    So, two years tells you something but not much.

    That's not a knock, it just too early to tell.

    First base will be along the lines of basically all that are still in operation and with acceptable maintenance / use going past the 10 year point with mileage anywhere between 20k and 150 - 200 k.

    Technically speaking there is an acceptable but minuscule failure rate / warranty pay etc allowance built in somewhere so as long as its at or below that - its a win..

    You round home when all of whatever constitutes Ford's most loyal 4.6L users including fleet, all give a thumbs up and want this in place of that.

    Takes time.

    Couldn't agree more.

    If the water pumps design is long life and the owner follows the servicing schedules, like they should do, i don't see any issues at all.

    Many vehicle problems are caused through abuse and a lack of care/servicing.
